Well, it's helpfull that your installation problem is repeatable, but unfortunately we've been unable to reproduce it here.
Running the 2.1.4 installer should automatically un-install the 2.1.3 code first. That part appears to be working.
Your trouble appears to be that running the installation (whether from the 2.1.4 installer or directly from the Add/Remove Programs control panel) - 'appears' to run to completion, but in fact - is not truely deleting files.
That suggests that something in your registry is corrupted.
Perhaps we could schedule a time when someone from our support team could look at the registry on your computer? Perhaps even run the installation manually - from the command line - so that we can get a debugging log?
If you are willing to try this, please send email with possible times when we could connect to your computer (you will need about 30 minutes and a high speed internet connection). Send email to support@RecordsForLiving.com.
Thanks,
Support Team.
